These numbers include both undeclared cannabis seized by the border agency and declared cannabis forfeited to officers. But the agency could not break the figures down further to indicate how many instances of each type of confiscation occurred.

As of last Oct. 17, adults in Canada can possess and share up to 30 grams of legal cannabis.

However, taking pot across Canada’s international borders remains illegal and can result in serious criminal penalties.

As a result, bringing cannabis into Canada is against the law even when travelling from places that have loosened their laws on marijuana use, and despite the fact that recreational consumption is now permitted in Canada.

In the weeks before legalization, the border agency advised the public that officers would be asking visitors and returning Canadians whether they have any cannabis with them. They hoped the question would reduce the risk of unintentional violations of the law.

If you are carrying pot when you enter Canada, it must be declared to the border agency. Otherwise, you may face arrest and prosecution, the agency says.

The newly released statistics do not indicate how many charges resulted from the 329 confiscations in the six-week period last fall.

The increase “doesn’t mean necessarily that it’s leading to a negative outcome for these folks,” said Mark Belanger, a lawyer with Border Solutions Law Group in Vancouver.

Belanger suggested it is too early to detect such post-legalization trends, and over the next year or two he will have “better anecdotal evidence” as to what is happening.

The border agency also saw a massive year-over-year jump in the number of cannabis interceptions through searches of parcels sent to Canada by mail during the six-week period.
